title: Study of the distributed thermal lens of LD end pumped rectangular gain.
abstract: In the LD end pumped rectangular laser gain medium, the thermal induced refractive index is not only non-uniformly transversely, but also non-uniformly and distributed along the pumping beam propagation, the effect of thermal lens is a distributed not a lumped lens effect as previously considered. In this paper, the effect of a distributed thermal lens is analyzed.
